摘要:
A digital signal recording apparatus and a method of operating the same, used in conjunction with TV and video cameras, for example for security applications, includes a disk feeder system having a disk recorder and an upper compartment for holding fresh unrecorded disks, a pull slider assembly which pulls a first fresh disk at the bottom of the compartment and places the same and a printing head assembly which imprints coded information onto the placed disk, a disk recorder having a sliding table for supporting the disk and a lower compartment which accommodates the recorded disks. Supported by the sliding table the recorded disk is retracted into the disk recorder which, after the completion of recording, generates a command signal to start a new cycle. An exclusive code is imprinted onto the surface of the disk and coded signals commensurate with the exclusive code are generated by a controller and mixed with the digital video signals recorded by the disk recorder to authenticate the recording of the disk outputted from the disk feeder system. The apparatus may be equipped with a pull lever which engages cutouts provided on a fresh disk tray to transport the tray containing fresh disks from a feeding position to a recording head.

The invention provides a method and apparatus for using a remote control device such as car key that generates unknown coded signal with other appliances, such as building's door, garage door or parking barriers, by demodulating and detecting time durations, sequence and other data pertaining the envelope of the unknown coded signal and storing the envelope data into a memory for comparing the stored envelope data with a data of an envelope of a newly received unknown coded signal and outputting match signal when the stored data and the newly received data match. The match signal can be used to operate locks, doors and barriers also in conjunction with systems including video interphone, alarm, emergency and access control system.

A method and apparatus for processing and digital recording video signal where transmitters for generating video signals receive an external synchronizing signal for synchronizing the transmitters. A recorder receiving the video signals has a switch sequentially connecting the transmitters to a digital video recorder. Code signals corresponding to identification codes allotted to video signals are generated. An injection circuit mixes code signals into video signals. The digital video recorder has a copy including circuit for time and date signal generating, for compressing the received signals and outputting them with the extracted codes and time and date of recorder signals to a memory storing those signals in endless cascaded rotation. Freshly stored signals replace the oldest signals stored in cascade. An alarm data signal for triggering the alarm state of the apparatus is received and the video signals recorded during the alarm state are recorded.

An apparatus for the selective routing of information signals includes a plurality of transmitting units. Each transmitting unit has a transmitter for transmitting information by converting the same into a light signal. A plurality of fiber optic lines are provided for carrying the light signal from the transmitting units. Each fiber optic line corresponds to one of the transmitting units. At least one receiving unit is provided for selectively receiving the information carried by the fiber optic lines. The receiving unit includes a liquid crystal panel having a plurality of light passing areas. The optical transmission properties of the light passing areas are controlled individually, for selectively receiving the light from the fiber optic lines, for effecting connections between the transmission units and the receiving unit by the fiber optic lines in any arbitrary combination. Each light passing area corresponds to one of the fiber optic lines. A receiver which is part of the receiving unit generates an electrical signal converted from the light which passes through the liquid crystal panel.

In a method and apparatus for coding, processing and retrieving a signal, a plurality of transmitters each including a television camera, generate composite video signals each superposed with an allotted identification code through a transmission line. A sequential switch circuit is provided which connects a plurality of the composite video signals for at least one vertical scanning period of the composite video signal in synchronized sequence with the vertical scanning frequency, and outputs the sequencing signals to a video recorder for recording the sequencing composite video signals superposed with the identification code. The played back regeneration signals are fed to a control circuit and to a memory circuit. The control circuit has a code setting circuit and an extraction circuit which extracts the identification code from the composite video signal for selecting any individually recorded signal when the extracted identification code and the set code coincide. The selectively outputted signal is fed to a memory for storing and retrieving the composite video signal for displaying an image on a television monitor on the basis of the retrieved signal.

In a method and apparatus for converting a synchronizing signal received from a controller for controlling a TV camera into a new synchronizing signal, a single frame synchronizing pulse for every two field pulses is generated on the basis of at least a vertical drive signal of the synchronizing signal received from the controller. The new synchronizing pulse which has a level higher than the white level and lower than the black level of a composite video signal generated by the TV camera is injected into a video transmission line connected to the TV camera for synchronizing the latter on the basis of the injected synchronizing pulse.

A closed circuit television apparatus comprises a remote-controllable television camera including an image pick-up device for generating a video signal, a plurality of controlling devices each having an operating circuit for generating a plurality of control signals to control the television camera, and a displaying device which receives the video signal and displays a picture or image corresponding to the received video signal, and a distributing device which connects the displaying devices of the respective controlling devices to the television camera for distributing the video signal from the television camera to the controlling devices. Each operating circuit outputs a modulated control signal of a carrier frequency higher than the frequency of the video signal, to a circuit portion connecting the distributing device to the displaying devices. The television camera also includes a driving circuit which receives the control signals, extract a separated control signal, demodulates and decodes the extracted signal and operates the television camera based on the decoded control signal.
摘要:
A method and apparatus for measuring and calibrating the power consumption reporting by intelligent AC outlets, sub outlets and sockets including optoport and RFID antenna using a hand held loader and propagating optical signals via a lightguide or fiber optic cable and via RFID signals and tags, including the setting up of location, AC outlet identification and appliance particulars. Simpler loaders or calibrators communicate standard power consumption values to the AC outlet for self-calibration using the received values. The appliance particulars are introduced via the loader keys or a touch screen and via the reading of a RFID tag attached to the plug of an appliance and processed via the loader for propagation through an optical grid of a residence automation system via current drain or power consumption receivers.

A method and apparatus for controlling the feed rate of a rectified AC pulses via a gated rectifier in a low DC voltage and current power supply is disclosed. The gated rectifier outputs gated AC pulses to an input capacitor via a current control diode and/or a zener diode and/or a resistor for charging the input capacitor to a voltage level and a charge capacity commensurate with the low voltage regulator and the low DC current drain. A gate capacitor for accumulating incremental charges of rectified AC pulses fed via a divider network is pre-configured to trigger the gated rectifier, timed by discharging the aggregated charge of a predetermined number of charges to the gate. The input capacitor charged by the gated AC pulses at a rate of one per said determined number to the input capacitor feeds the voltage regulator for powering a low DC current consuming device.
